This exciting collection brings together the major writings of the important English orientalist, Guy Le Strange. The set includes his valuable yet lesser known work: his translation of 'Nuzhat al-Qulub' - the most accurate assessment of the state of Iran in the early post-Mongol period; his translation of Ibn Serapion - a pioneering work on the changing river systems and canals in the Islamic period, a factor that played a key role in the fate of this part of the medieval world; and finally his work on al-Balkhi's account of Fars, which includes a unique account of Kurdish tribes in this province of Iran. Introduced by leading international scholar, Hugh Kennedy, this unparalleled collection will be of immense value to contemporary scholars of the medieval Arab world.
